OMAP: UART: don't resume UARTs that are not enabled.
Add additional check to omap_uart_resume_idle() so that only enabled (specifically, idle-enabled) UARTs are allowed to resume. This matches the existing check in prepare idle. Without this patch, the system will hang if a board is configured to register only some uarts instead of all of them and PM is enabled.
